Access openings and ramps for boats are detailed. Collar assemblies may include segments split in one or more ways and adapted to unfold, or otherwise open, along the splits to form ramps extending outward from the hulls of associated boats. Alternatively, portions of the segments may be removable. Boats with rigid hulls and foam (or other) fenders may include hinged segments of the hulls and fenders that open both to expose access openings into the boats and create ramps.
